If you leave either or both of these blank, the software will fill them in with the monitors native value. This is almost always what you want on the black, but usually its desirable to establish a white value below the monitor's ceiling value. The base reason is to allow headroom so you can continue to calibrate to these settings over time, as the monitor dims a bit, and can't reach the same max value. But most LCDs also run too bright for their ambient light/proofing light conditions, and need to be dimmed for print matching purposes as well as headroom.
